Answer engines don’t always pass a referrer. Apps, in-app browsers and copied links strip it, and Google files AI Overview clicks under Organic. Those visits land in the wrong channel, and AI search looks like it isn’t working. Vembel puts each one back under the engine that sent it.

Three sources of truth, joined into one ledger

Vembel joins what happens on your site, at your edge and in your revenue tools, so every AI-referred sale has a paper trail.

  1. Step 1

    Add the tag

    One lightweight, first-party script records sessions and landing pages. No cookies required.

    <script async
  src="//vembel.com/v.js"
  data-site="halden.run">
</script>
  2. Step 2

    Stream your edge logs

    Connect your CDN or host, so Vembel sees AI crawlers and the live fetches engines make while someone is asking.

Questions, answered

How can you attribute a visit that arrives without a referrer?

Three signals. When an engine fetches a page live while someone is asking (ChatGPT-User, Perplexity-User, Claude-User), it shows up in your server logs, and the visit that lands on the same page seconds later is matched to it. Landing patterns and in-app browser signatures cover the rest. Every match carries a confidence score, and you decide the threshold that counts.

Does Vembel replace Google Analytics?

No. Vembel sits next to GA4 and your CRM. It reclassifies AI traffic and sends it back as a clean channel, so the reports you already use get more accurate instead of being replaced.

Which AI engines do you cover?

ChatGPT, Gemini, Claude, Perplexity, Google AI Overviews and AI Mode, Microsoft Copilot, Grok, DeepSeek and Meta AI, plus the crawlers and agents behind them. New engines are added as they start sending traffic.

How is this different from AI visibility tools?

Visibility tools run prompts and report whether you were mentioned. Vembel starts from your own traffic and revenue and works backwards to the answers that produced them. Many teams use both: visibility to find opportunities, Vembel to prove which ones paid off.

What do I need to install?

A lightweight script on your site, a log stream from your CDN or host, and a connection to where revenue lives, such as Shopify, Stripe or your CRM. Nothing on your pages changes.

Is it privacy-friendly?

Vembel is first-party and works without cookies. Attribution never needs personal data: journeys are joined on session and order IDs you already own.

How is it priced?

By monthly sessions. Book a demo and we will quote it for your traffic, with preferred terms for early design partners.
